The 45° inclined viewing TU-12011C-230 PrepScope 2 Microscope with Achromatic Objectives from Ken-A-Vision features 4x, 10x, and 40xS achromatic objectives, and a 360° rotating head. The 40xS objective is spring-loaded. Both the turret and the included objectives adhere to DIN microscope objective standard. This means that you can use any DIN objective with this microscope without worrying about your microscope ever becoming obsolete. With a wide field 10 x eyepiece, the microscope provides a total magnification of 40x, 100x, and 400x. The supplied Achromatic objectives reduce color distortions introduced by imperfections in optical elements better than regular objectives and provide higher contrast images. The lenses are also coated with special coatings that protect their surfaces against mold in high humidity and high heat regions. The parfocalled and parcentered design allows for switching objectives without having to realign your sample and without losing focus. The focusing system has a coarse focus adjustment with rubberized knobs for a slip-free grip. To view details of our specimens more easily, the microscope features a white LED illumination system with adjustable brightness and a separate switch. The bright white light from the bottom LED emitter is focused with a light shaping lens and can be further collimated using a diaphragm with five apertures of different sizes.

The microscope also features a 4.25 x 3.75" aluminum stage with two spring-loaded clips for holding your specimen slides securely. The frame of the microscope is made of cast aluminum with white enamel finish. Included with the microscope are a USB cable, a wall charger, three rechargeable AA batteries, and a dustcover. To recharge your microscope's batteries, just connect the microscope's USB cable to the wall charger or a USB port.
